What are the characteristics of electrolyte in different batteries

1. The characteristics of the electrolyte of lead-acid batteries The electrolyte of lead-acid batteries is a dilute sulfuric acid solution prepared by adding concentrated sulfuric acid with water. The quality of the electrolyte has a great influence on the service life and capacity of the battery. The purity of the electrolyte has a great influence on lead-acid batteries, so different types of batteries use different sulfuric acid. Generally, dry-charged batteries do not require high levels, and only use sulfuric acid for batteries; valve-regulated sealed batteries have to Use decomposed pure sulfuric acid. 2. Characteristics of lithium battery electrolyte The lithium battery electrolyte is mainly composed of three types of substances: lithium salt, solvent and additives. The basic composition of the electrolyte has not changed much. The key to innovation is the current development of new lithium salts and new additives, as well as an in-depth understanding of the interface chemical processes and mechanisms involved in lithium batteries. 3. The characteristics of nickel-hydrogen battery electrolyte. Ni-MH batteries use the same or similar electrolyte as nickel-cadmium. Nickel-cadmium is usually potassium hydroxide. The nickel-hydrogen electrode is magical and consists of nickel, cobalt, manganese, aluminum and rare earth metals. It is also used for lithium batteries. Regarding the sealed nickel-metal hydride battery, the total amount of electrolyte will not generally decrease, but after repeated use or long-term storage, the electrolyte will be redistributed in the battery, and most of the electrolyte will be distributed to the positive and negative electrode plates, and the electrolyte in the diaphragm Reduce or even dry up, leading to an increase in the internal resistance of the battery. 4. The characteristics of nickel-cadmium battery electrolyte The electrolyte in nickel-cadmium battery is alkaline electrolyte. Most nickel-cadmium batteries are cylindrical, in which several layers of positive and negative materials are wound into a roll. The flooded nickel-cadmium version is used as marine batteries in commercial aircraft and UPS systems, operating in hot and cold climates where frequent riding is required. Nickel cadmium is more expensive than lead acid, but it lasts longer. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
